Abstract
The invention relates to a method for manufacturing an inductive electric component, such as inductor, coil, resistor, or the like, which comprises at least one spiral or coiled element (10), and the spiral or coiled element is formed from a piece furnished with cooling ribs (11). The invention also relates to an inductive electric component that comprises a piece (10) formed of material furnished with cooling ribs (11).
Description
Technical field
The present invention relates to a kind of method that is used to make such as inductance components such as inductor, coil, resistors, described inductance component comprises element at least one spiral or coiling.The invention still further relates to a kind of inductance component of the type.
Background technology
For example, inductance component may be an inductor, and for instance, it uses as filtering device in electric device.The conductor number of turns, external dimensions and employed core material influence the induction coefficient of inductor.
Usually, element spiral or coiling is to be made by the filamentary material that is coiled on the core material.No magnetic core element also can be coiled on the supporting construction.
This conventional disc around problem be a large amount of hand labours and the cost that causes thus, and be difficult to cool off thick coil, be difficult to the water cooling of arranging relatively unless particularly use.
Summary of the invention
Therefore, the objective of the invention is to propose a kind of can solution to the problems described above and inductance component.This purpose is to realize by method of the present invention and inductance component, it is characterized in that, forms element spiral or coiling by the parts that are furnished with cooling ribs, and forms described element by the water cutting.
For example, this can be inductor or resistor element, it cuts into " spring-like " by sheet material with selected thickness or tubulose section bar water, and in this case, raw material for example can be extruded aluminium section, copper rod and pipe and the stainless steels with different wall.Then, make at least one surface arrangement of sheet material that cooling ribs be arranged, perhaps make the inner surface of tubulose section bar and at least one in the outer surface be furnished with cooling ribs.
In the manufacture process of element, method of the present invention provides effective air cooling for this element, and the modern method that water cuts with the minimum hand labour of needs provides accurate in size product.Described method very flexibly and be easy to be applied to different component shapes.This product is easy to be applied to different electric currents, and can make even very little coil.
The width of water cutting groove is preferably 1 to 2mm.Especially, preferably fill up varnish or resin by the narrow cutting groove of the element of sheet material cutting, this varnish or resin are bonded as fuel plate again with parts.Cutting element also can be used mechanical support.
If necessary, for example, can increase the current strength of inductor by a plurality of helical coils that are connected in parallel.Correspondingly, can increase the induction coefficient of inductor by a plurality of helical coils that are connected in series.
The water cutting of preferably using in the method is suitable for material miscellaneous, and for example compares with laser and can be used for cutting thicker material.The water cutting can not produce heat in the material cutting, this means that material can not be out of shape in cutting process.In the water cutting, utilize the thin injection water of about 1000 meter per seconds, make material to be cut by being penetrated to its high-energy-density of concentrating.Utilize the high-pressure pump that produces high pressure that this injection water is provided.The water cutting is very effectively and is very easy to the method for control.In the material processed process, can the generating material burning or fusing, gas or molten slag form, break, fracture or chemical change.The outlet side of injection water also can remain intact harmless.The water cutting can use two kinds of technology to realize: perhaps only utilize water, perhaps by add frosted in water.When using frosted, go out hard sand crystal from the injection water of injector, therefore can cut all hard and firm materials.
Description of drawings
Next, the present invention is described with reference to the accompanying drawings, wherein
Fig. 1 to 5 shows the different execution modes of the inductance component of the present invention that is furnished with cooling ribs.
Embodiment
Fig. 1 shows the stereogram of element 10 of the inductance component of the present invention of flat spin shape, and this element is to form by carried out the water cutting by sheet material, and this sheet material all is furnished with cooling ribs 11 on both sides.In this way, the element 10 of cutting has also obtained cooling ribs, and need not any extra procedure of processing.The perforation tie point 12 that is used to be electrically connected is formed on the front end place of element 10 centres and the end at its edge.Surface away from these tie points 12 processes cooling ribs, to guarantee better to connect contact.The groove of water cutting is marked with Reference numeral 13.
Fig. 3 shows the coiling element 30 of inductance component of the present invention in three-dimensional mode, and it is to form by carried out the water cutting by the tubular log material, and described tubular log material all is furnished with cooling ribs 31 on inner surface and outer surface.At place, the end of element 30, the hole 32 that is formed for being electrically connected, and as the execution mode among Fig. 1 and 2, this hole 32 surperficial processed smooth.Utilize the water cutting groove 33 of constant size to obtain coiling band accurate in size, constant width.The width of the spacing of helical and element 30 is easy to be embodied as required size.Be equally applicable to the thickness of element 30.
Fig. 4 illustrates the end-view of coiling element 40, and coiling element 40 is corresponding to the inductance component among Fig. 3 30, and its difference is that cooling ribs 41 only is positioned on the inner surface of element 40 herein.
End-view shown in Fig. 5 shows coiling element 50 then, and coiling element 50 is corresponding to the inductance component 30 of Fig. 3, and its difference is that cooling ribs 51 only is positioned on the outer surface of element 50 herein.
Preferably, cutting groove can be full of varnish or resin respectively to support this element.
Above description of the present invention only is used to illustrate basic thought of the present invention.Therefore, those skilled in the art can change its details within the scope of the appended claims.
